The most distant object ever seen in the known universe has been spotted by the Hubble Space Telescope - a galaxy that is 13.4 billion light years away.
An iconic image from the Hubble telescope: The Pillars of Creation, located at the heart of the Eagle Nebula. The Pillars are gaseous nurseries for newborn stars
The light we see from the galaxy began its journey through space just 400 million years after the Big Bang gave birth to the universe.

The discovery has shattered the cosmic distance record set byastronomers.

The distance to the galaxy, known as GN-z11, was measured by splitting its light up into its component colours.

Because of the expansion of the universe, distant objects flying away from us have their light stretched to the red end of the spectrum - a phenomenon known as "red shift".
Dark lanes of dust crisscross the giant elliptical galaxy Centaurus A. At a distance of just over 11 million light-years, Centaurus A contains the closest active galactic nucleus to Earth. The center is home for a supermassive black hole that ejects jets of high-speed gas into space, but neither the supermassive black hole or the jets are visible in this image
The larger an object's red shift, the further away it is.
Previously a galaxy called EGSY8p7 held the red shift record, a figure of 8.68. But GN-z11 has a red shift of 11.1, corresponding to just 400 million years after the universe began.
NGC 6302, also called the Butterfly Nebula, is a bipolar planetary nebula in the constellation Scorpius
Dr Pascal Oesch, a member of the team from Yale University in the US, said: "We've taken a major step back in time, beyond what we'd ever expected to be able to do with Hubble. We managed to look back in time to measure the distance to a galaxy when the universe was only 3 per cent of its current age."
The Big Bang is thought to have brought everything that now exists into being around 13.8 billion years ago.
